I have attached a diagram of what we are planning at the moment.  The functions ReadConfigFile() and WriteConfigFile() would be called when the user requests a load or save.  The configuration data would be stored in one big structure.  GetData() returns a pointer to the structure, and is intended as the link between the PVs and the library.
